Maybe that means If you ID often you get more spots on RBN, but not win the contest. Not surprising ID is been coming old fashion on Contesting and no-ID for several Qs turning to be great skill amon
One of my posts was censored so I repeat again - the main problem of RBN are cheap QSD 0IF RX with I/Q images due to sampling in the middle of CW bands. Just make QS1R requirement for RBN connection
Real life 0IF RX could achieve 60 dB unavoidable image rejection and this is not enough in contests. Our ham freqs are NOT channelized although one knows where the image is! The most popular version

Let's ignore all the mechanisms responsible for wrong-frequency RBN spots, shall we? That should have been: Let's ignore all the OTHER mechanisms for wrong-frequency RBN spots, shall we? -ex-VR2BG/p.
Bret, I've asked you twice now please to share your data and methods, and you haven't even responded to my e-mails. Sharing information is essential to any solution. The RBN team has developed a beta

Jose, CT1BOH analyzed 109 bust spots out of 8114 DR1A spots, mere 1,34 % ! This is much better than humans 3 % average. QSD I/Q images and harmonic relations are well known phenomena. BPF help even s

Boy, imagine if this thread would have started 10 yeas ago. People would have thought we were nuts talking about how computers can copy callsigns better for us :-) 73 Tom W7WHY --{snip}-- Though it s
I have gone through the same process that Bret describes, and found only a couple such instances out of thousands of spots on one day. So I guess I need to ask again - will you make your methods and
